| 中文摘要 |
| 研究了染料高效吸附菌(青霉菌BX1)的生长条件及其对活性艳蓝KN-R的吸附特性为避免染料对其生长的毒害,本研究将菌体培养及其对染料的吸附分离.结果表明,青霉菌BX1生长分3个阶段:孢子活化、线性生长和菌体自解.菌体生长的最佳温度为30℃,最优碳源依次为淀粉＞木糖＞蔗糖＞麦芽糖＞葡萄糖＞乳糖,最佳pH值为4.0用培养48h的活菌体吸附水中的100mg/L的活性艳蓝KN-R,120min脱色率达93.7%,20℃时菌体(以干菌重计)对染料的最大饱和吸附量为159mg/g. |
| 英文摘要 |
| The biomass of Penicillium oxalicum BX1 could adsorb many kinds of dyes. The effect of temperature, carbon source and pH on its growth and its adsorption to Reactive Blue KN-R were studied. To avoid the toxicity of the dye on BX1 biomass growth, BX1 culture and its adsorption to the dye were separated. It was found that there were three phases during BX1 growth: spore activation, linear growth and decay. The rate of BX1 growth in different carbon sources followed the order of starch > xylose > sucrose > maltrose> glucose > lactose. The optimum pH value of BX1 growth was 4.0. The decolorization rate for KN-R was 93.7% after 120min adsorption. The maximum adsorption capacity (Reactive Blue KN-R/dry biomass) was 159mg/g in 20℃. |
